Insurgency:Modding Overview

Insurgency is based on Source Engine, which is known for it's "modability."

In addition to the Hammer level editor, model compiling and texture format tools available for Source Engine and heavily documented on Valve's Source SDK docs, New World Interactive has opened up Insurgency to modding in other ways - most notably with advanced scripting which allows modders to create total conversions without compiling a single line of code.
